Key timeframes in Western Australia

1

Serve the payment claim (section 22)

You must serve it in time: The later of the contractual date or 6 months after the work was last carried out or the goods last supplied (section 23). Final payment claims have their own window.

2

They respond — 15 business days (section 25)

The respondent has 15 business days after the payment claim is made, or the time required by the contract, whichever is earlier (section 25).

3

If they do not respond

If no payment schedule is given in time, the respondent becomes liable to pay the claimed amount on the due date (section 26). A respondent that gave no schedule also cannot file an adjudication response or seek adjudication review.

4

Adjudication (section 28)

20 business days after the claimant first becomes entitled to apply (section 28). The application is made to the adjudicator named in the contract if it names one, or otherwise an authorised nominating authority chosen by the claimant.

5

Keep records

Keep copies of invoices, evidence, service records and correspondence. Proof of when and how the claim was served is what the timeframes above run from.

What is different about Western Australia

Which Act applies depends on when the contract was signed. The 2021 Act covers contracts entered into on or after 1 August 2022. Earlier contracts remain under the Construction Contracts (Former Provisions) Act 2004, which is a different regime with different deadlines. Western Australia also keeps an adjudication review that the eastern states do not have, and excludes some smaller home building work.

Statutory references on this page were checked against the consolidated Building and Construction Industry (Security of Payment) Act 2021 (WA) on the official Western Australia legislation website in July 2026. Timeframes interact with your contract and with the statutory due date for payment, so check your own contract. This is general information, not legal advice.

The Act that applies in Western Australia

Western Australia is covered by the Building and Construction Industry (Security of Payment) Act 2021 (WA) for construction contracts entered into on or after 1 August 2022, and by the earlier Construction Contracts (Former Provisions) Act 2004 (WA) for contracts made before then. Like every Australian state and territory, Western Australia has its own Security of Payment legislation giving contractors, subcontractors and suppliers a statutory right to recover money owed for construction work — without first going to court.

Western Australia uses a different adjudication model to the east-coast states — payment timeframes are set by the contract or, where the contract is silent, by the Act. PayClaim accounts for these differences when preparing your claim.

Whatever your trade — electrician, plumber, concreter, carpenter, roofer, painter, tiler, scaffolder, formworker, earthmover or supplier — if you’ve performed construction work in Western Australia and you’ve issued an invoice that hasn’t been paid, the WA Security of Payment legislation is the legal lever built for your situation.

Who can use a payment claim in WA

  • Subcontractors of every trade working on commercial, residential and civil projects
  • Head contractors and licensed builders chasing unpaid progress claims
  • Suppliers of construction materials, goods or related services
  • Plant hire, scaffolding, formwork, earthmoving and related construction services
  • Consultants and design professionals providing construction-related services
  • Sole traders and small construction businesses operating across Perth and across regional WA

What you need before starting

You don’t need to know the legislation to use PayClaim — you just need a few details about the job and the unpaid invoice:

  • The invoice you’ve issued and any contract, quote or purchase order if you have one
  • The debtor’s business name, ABN (if known) and a contact email
  • The project or site address in Western Australia
  • A short description of the construction work performed
  • Any supporting evidence — site photos, sign-off emails, variation documents

What PayClaim does for you

For a flat $69, PayClaim:

  • Prepares a formal payment claim under the WA Security of Payment legislation, with the statutory notice wording the Act requires
  • Itemises the amount claimed and references your supporting documents
  • Serves the prepared claim electronically on the respondent on your behalf
  • Records and emails you proof of service
  • Calculates the response-deadline date based on the rules in Western Australia and the details of your claim
  • Alerts you as the deadline approaches so you can act if the respondent doesn’t respond or doesn’t pay

Response deadlines depend on the state, the contract and the type of claim — PayClaim calculates the relevant deadline from the information you provide so you don’t have to.

What happens after the claim is served

Once served, the respondent has a statutory window under the WA Security of Payment legislation to either pay the claimed amount or formally respond setting out what they’re paying and what (if anything) they’re withholding. If they pay in full, you’re done. If they don’t respond, the unpaid amount may become a statutory debt enforceable through the courts. If they dispute the claim, you have the option to apply to a registered adjudicator for adjudication — a fast, lower-cost alternative to court.

PayClaim is built for the prepare-and-serve step. For complex disputes, adjudication strategy, court enforcement or insolvency-related matters, you should seek advice from a qualified construction lawyer in Western Australia.

How Security of Payment works in Western Australia

Security of Payment gives you a fast, statutory path to be paid for construction work — separate from, and quicker than, court. Under the Building and Construction Industry (Security of Payment) Act 2021 (WA) (which applies to contracts entered into on or after 1 August 2022) the process runs like this:

  • 1. Serve a payment claim. A payment claim is served on the party who owes you, identifying the construction work and the amount claimed.
  • 2. The other side responds. They can pay in full, or serve a payment schedule stating how much they propose to pay and why they are withholding the rest.
  • 3. No conforming response. If they fail to respond in time and do not pay, the claimed amount can become recoverable as a debt, and the door to adjudication opens.
  • 4. Adjudication. A registered adjudicator can decide the amount quickly — usually far faster and cheaper than court — and the determination can be enforced.

Contracts entered into before 1 August 2022 run under the older Construction Contracts (Former Provisions) Act 2004 (WA), which uses a different timeframe and process. Western Australia also has an adjudication review step that the eastern-state schemes do not. PayClaim identifies which regime applies from the details you provide.

Adjudication in Western Australia

Adjudication is the engine of the Security of Payment scheme: a rapid, independent determination of how much you are owed, made by a registered adjudicator rather than a judge, designed to keep money moving on construction projects.

In Western Australia an adjudication application is made to the adjudicator named in your contract or, where the contract does not name one, to a registered adjudicator or prescribed appointer. The determination is binding and enforceable, typically costs a fraction of litigation, and is decided in weeks rather than months. If you need to lodge one, our adjudicators guide sets out the pathway for each state and territory. PayClaim prepares and serves the payment claim that starts this process; running the adjudication itself, or any court enforcement, is a separate step you take yourself or with a construction lawyer.

Common questions about Security of Payment in WA

How does Security of Payment work in WA?

You serve a payment claim for the construction work you are owed. The other party pays, or serves a payment schedule setting out what they dispute. If they do not respond in time, the amount can become payable and you can apply for adjudication — a fast, independent decision that can be enforced like a debt.

Which Act covers Security of Payment in Western Australia?

The Building and Construction Industry (Security of Payment) Act 2021 (WA) covers construction contracts entered into on or after 1 August 2022. Contracts made before that date are covered by the Construction Contracts (Former Provisions) Act 2004 (WA).

How do I apply for adjudication in WA?

If your payment claim is disputed or unpaid, you apply to the adjudicator named in your contract, or otherwise to a registered adjudicator or prescribed appointer, within the timeframe the Act sets. The adjudicator makes a binding determination of the amount owed.

How long does the other party have to respond to a payment claim in WA?

The response window depends on the applicable Act and your contract. PayClaim calculates the exact response deadline for your claim from the details you provide and reminds you as it approaches. This is general information, not legal advice.

Do I need a lawyer to make a Security of Payment claim in WA?

No. The scheme is built so contractors and subcontractors can use it without a lawyer. PayClaim prepares and serves a compliant payment claim for a flat $69. For a complex dispute, adjudication strategy or court enforcement, a construction lawyer is worth engaging.
